缪刺考

At present, most physicians hold that Miu Ci is "left and right cross collateral prick-ing",but it does not conform to the original meaning of "Suwen·Miucilunpian"(Plain Questions ·Trea-tise on Miu Ci). Miucilanpian holds that Miu Ci is the extension and perfection of Ju Ci (contralateral me-ridian needling), which mainly pricks the collateral but is not limited to the collateral, as it also pricks the acupuncture point. As for the "left and right cross" point selection, it is one step in the procedure of the treatment in the process of contralateral collateral needling instead of being a principle.

 【目的】 应用抗PBP2a单克隆抗体,以化学交联法致敏羧化聚苯乙烯乳胶,建立快速检测MRSA-PBP2a的乳胶凝集法?【方法】 以辛酸-硫酸铵法纯化PBP2a单克隆抗体,将纯化后单克隆抗体和羧化乳胶经碳化二亚胺(EDC)共价偶联,并对偶联条件(偶联抗体浓度?乳胶浓度?偶联时间和偶联缓冲液)进行探索和优化,建立检测PBP2a的乳胶凝集法?【结果】 140 mg/L的抗体浓度与15 g/L的羧化聚苯乙烯乳胶,在pH 5.8缓冲液中偶联8 h后有较好的凝集效果和偶联效率,所建立的乳胶凝集法敏感性和特异性良好?【结论】 初步建立了检测PBP2a的胶乳凝集法,为研制MRSA快速鉴定试剂盒奠定了良好的基础?     

晚发型新生儿败血症院内感染和社区感染的病原菌对比与分析

目的 晚发型败血症是新生儿期常见的感染性疾病,也是新生儿死亡的常见原因之一.新生儿一旦感染,病情可以迅速恶化,故早期有效的抗菌素治疗至关重要.该研究的目的 就是通过回顾性地分析晚发型新生儿败血症(LONS)的病原菌及其药敏,以指导临床早期对可疑LONS患儿合理用药.方法 对2002年1月1日至2005年12月31日温州医学院附属育英儿童医院NICU收住的具有临床表现以及至少一次血培养阳性的LONS临床特点、药敏进行回顾性分析.结果 102例LONS多通过皮肤、消化道、呼吸道等途径感染,临床表现无特异性.其中院内感染22例,社区感染80例,院内感染组与社区感染组比较,患儿胎龄小,体重轻,发病早(t=2.255、P＜0.01,t=8.818、P＜0.01,t=7.581、P＜0.05),差异有统计学意义.两组患儿血培养共检出110株病原菌,以凝固酶阴性葡萄球菌(CNS)居首(50/103,48.5%),其次为肺炎克雷伯杆菌(16/103,15.5%)、金黄色葡萄球菌(9/103,8.7%).社区感染主要病原菌为葡萄球菌属和大肠埃希菌,院内感染则为肺炎克雷伯菌.大部分(＞80%)的葡萄球菌尤其是CNS对青霉素类、红霉素及头孢唑啉耐药,MRSA达66.7%(6/9),但对万古霉素未发现耐药,大部分对利福平亦敏感.几乎所有(15/16)的ESBLS肺炎克雷伯菌具多重耐药性,仅对碳青霉烯类、氨基糖苷类以及喹诺酮类等少数抗菌药物敏感.发现1例对万古霉素耐药的粪肠球菌,然而,未发现B组链球菌感染的病例.结论 LONS临床表现非特异性,B组链球菌不是温州地区社区感染LONS的主要致病菌.由于医院和社区抗菌素的滥用,出现越来越多的多重耐药菌.对于可疑败血症患者应常规进行血培养以确定病原菌,并根据最可能的病原菌选用相关抗生素.为减少多重耐药菌感染的发生,应尽量减少第三代头孢菌素的使用.     

儿童重症监护室呼吸机相关肺炎病原学分析

目的:探讨儿童重症监护室(PICU)呼吸机相关肺炎(VAP)的临床病原学特点。方法:对156例PICU机械通气患儿的临床资料、病原菌构成和药敏试验结果进行分析。结果:156例机械通气患儿中,66例发生VAP,发生率为42.4%,早发性VAP病原菌以革兰阳性菌为主,晚发性VAP以革兰阴性菌为主,耐药性较高。结论:明确VAP的发病因素和致病菌,有利于合理使用抗生素,预防VAP。     

医院感染病原菌对抗生素和消毒剂的交叉耐药

葡萄球和革兰阴性菌是医院感染的重要病原菌常引起医院感染的爆发和流行.这些常见病原菌对抗生素和消毒剂产生交叉耐药的情况在临床上不少见,并且具有多种耐药机制.常见病原菌交叉耐药情况及其机制的研究,对临床抗生素和消毒剂的合理使用以及医院感染的控制具有重要意义.     

Tolerance of the cirrhotic liver to normothermic ischemia. A clinical study of 15 patients

Temporary occlusion of hepatic inflow, namely, the Pringle maneuver, was adopted for 15 patients with liver cirrhosis who underwent partial hepatectomy. The warm ischemia time ranged from 2 to 32 minutes with an average of 19 minutes. The procedure did not cause any harmful effects on systemic hemodynamic and postoperative liver function. The results in our patients were compared with those of 15 comparable control patients who had been operated on over the same period of time without inflow obstruction. The Pringle maneuver significantly diminished the estimated blood loss during surgery, intraoperative and postoperative complications, and suppressed the operative mortality rate from 20 percent to 0.     

小儿肺炎支原体感染诊断及发病机制探讨

探讨小儿肺炎支原体（Ｍｐ）感染的敏感诊断方法与发病机制。方法采用聚合酶链反应（ＰＣＲ）技术检测咽拭子Ｍｐ－ＤＮＡ，同时做血清冷凝集试验（ＣＡＴ），对４９８例呼吸道感染的住院患儿进行配对资料研究，４８例测定了有关免疫指标。结果ＰＣＲ法阳性率为３７．５５％（１８７／４９８），ＣＡＴ法阳性率为１０．０４％（５０／４９８），二法差异有极显著性意义。３～１０岁组感染率明显高于３岁以下组与１０岁以上组。ＰＣＲ法不受自然病程的影响，ＣＡＴ法明显受到病程的影响。１２例Ｍｐ－ＤＮＡ－ＰＣＲ和循环免疫复合物（ＣＩＣ）均阳性者多伴有肺外并发症。结论ＰＣＲ法是早期诊断Ｍｐ感染的敏感方法，明显优于ＣＡＴ法。感染可能与Ⅲ型变态反应参与的免疫介导损伤有关

Familial focal loss of cross striations

Summary Two patients, a brother and sister, both suffering from congenital generalized muscle weakness with a progressive course are reported. Muscle biopsy revealed areas with loss of cross striations in the muscle fibers, electronmicroscopically presenting complete disorganization of the myofibrils with streaming of the Z discs and absence of mitochondria. Vesicular nuclei with prominent nucleoli were present in these areas. There was a type I fiber prodominance in both cases. The mean diameter of the type I muscle fibers in one of the cases was too small. Motor endplate alterations in this patient gave no evidence of denervation but were suggestive of a delayed development of motor nerves.This study was supported by grants from the Prinses Beatrix Fonds, from the FRSM of Belgium and from the Free University of Brussels
